Arcade style racing games aren't exactly a dime-a-dozen nowadays so whenever one comes around it's generally a nice change of pace. In Proun you race on a single small wire as a sphere while avoiding obstacles by rotating. The game has a huge sense of speed and evading in a circular motion can be a bit dizzying for some. You use the arrows keys or WASD to rotate your sphere and control its speed. The shift key will activate a boost that you can gain by avoiding obstacles for a certain amount of time. You can choose the speed of the game, but the lowest setting is "Fastest" so regardless of what you play at you're going to need some quick reflexes to avoid obstacles. There aren't any audio cues within the game that aren't accompanied by strong visual cues as well. The menus as well as the in-game HUD are clear and easy to read and color is never an issue.
